Synonym discussion
Sense: noun/1
Gel, cream, lotion, balm, and ointment all sit on a bathroom shelf and all rub onto skin or hair, but they differ by texture and use. Gel is the runniest of the solid-looking products: clear, soft, jelly-like, and quick to rub in — Taiwan readers will picture aloe gel after a sunburn or hair gel for a school-day style. Cream is thicker and usually opaque, so it sinks in slowly and feels richer; people pick it for dry skin in winter. Lotion is the most liquid of the group, runny enough to pour from a bottle, used for whole-arm or whole-body moisturising. Balm is waxier and more solid at room temperature, often for lips or small sore patches. Ointment is the most medicinal: a greasy, sticky layer doctors prescribe over a cut or rash. So gel = light and clear; cream = thick and creamy; lotion = pourable; balm = waxy; ointment = greasy and medical.

Etymology
Gel is a short, modern word made from the longer scientific term gelatin in the late 1800s. Gelatin itself goes back through French gélatine to Latin gelatus, meaning 'frozen' or 'set firm', and that Latin word is also the root of jelly. So gel, jelly, and gelatin are all close cousins describing something that has cooled into a soft, wobbly state. The shorter form gel started in chemistry labs as a tidy way to label this physical state, and from the mid-1900s it spread to everyday English to name hair products, shower products, and sports energy packs that share the same jelly-like feel.
